SHUTTLE-=BOX FOR LOOlVlS.

SPECIFICATION forming part of Letters Patent No. 365,683, dated June 28,1887.

Application filed January 22,1887. Serial No. 225,132. (No model.)Patented in England July 15, 1886, No. 9,200.

To (ZZZ whom it may concern:

Be it know n that I, JAMES HOLLINGWORTH, a subject of the Queen of GreatBritain, resid ing in Dobcross, in the county of York, England, haveinvented certain new and useful Improvements in Shuttle-Boxes for Looms,of which the following is a specification.

My invention has special reference to shuttle-boxes arranged in tiersone above another, and mounted on the ordinary lathe-sword or goingpart, being raised or lowered so as to bring each time the requiredshuttle opposite the picker. Such shuttle-boxes have hitherto usuallybeen made by casting them of metal, a method which, because of theirpeculiar shape and construction, is very expensive, since they aredifficult to mold in the sand, and when cast a great deal of labor isrequired to finish them and render them fit for use.

The object of my invention is to provide a cheaper and betterconstruction of shuttleboxes. To this end I construct them of metalplates stampedout in the required shapes, and afterward joined togetherby riveting or other means of fastening.

My improved shuttle-box consists of a back.

plate of metal cut out to the proper shape, and having its top andbottom portions bent at right angles, the one to constitute the top ofthe box and the other the bottom thereof, said back, top, and bottombeing provided with fastening slots and projections. The shelves ordivision-plates between the several shuttlecompartments are likewise cutout of metal plate, and are j oined' to the back plate by riveting.Against the frontare placed two cast-metal front plates-one at eachend-and the shelves and top and bottom are riveted to them. To one ofthese plates the swells are hinged, and the other plate carries stopsfor confining the free ends of the swells. The swells are hinged on apin, and theirknuckles are housed in a swell east upon the front plate,which prevents their pivot'holcs wearing un evenly.

Figure 1 of the accompanyingdrawings is a front elevation of a tier ofshuttle-boxes constructed according to my invention. Fig. 2 is an endelevation thereof, partly in section, on theline 2 2 in Fig. 1. Fig. 3is a plan thereof.

Fig. 4 is an elevation of the cut plate which E and F are the frontplates, and G G are the swells.

The shuttle-box is made in the following manner: There is cut or stampedout from sheet-steel or other metalplate a piece, 0, of the requisiteshape, as shown in Fig. 4,'having holes or slots a a in it andprojections Z) I) on its opposite edges. This plate is bent up at rightangles on the line L M in Fig. 4, in order to form the top Z, Fig. 2, ofthe shuttleboxes, and is likewise bent up on the line 0 P in Fig. 4, inorder to form the bottom or lower shelf, at, thereof, Fig. 2. A numberof plates, D, of the shape shown in Fig. 5, are also out out of sheetmetal to'form the shelves or division-plates. These have projections b bon their back edge, which fit into the slots a a in the plate 0, andwhich, being inserted therein, are riveted down on the back thereof.They also have projections b I) on their front edges, corresponding inposition to the projeetions b b on the top and bottom portions, Z and m,of the plate 0. The front of the shut tle boxes is left open, except atthe ends, which are covered by front plates, E and F. (Shown detached inFigs. 6 and 7.) These plates are made with slots a a to receive theprojections 11 b on the shelves D and on the top and bottom Z m of theplate 0, which projections, on being inserted in said slots, are riveteddown, thereby securing the several parts firmly together. These platesare preferably cast,in order that they may readily be made of varyingthicknesses. They may be of cast-iron or steel, or of malleable iron orother metal. They are made somewhat thicker than the plates 0 D, and arethickened around the slots a a, in order that these slots may be beveledor countersunk on their front sides, as shown. Thiscountersinkingoftheslotgives theriveted head a dovetail form, which isstronger than a mere straight rivet. The plate F is curved outwardly atits end 9, for the purpose of guiding the shuttle into the boxes in caseit is not. thrown exactly true. The shuttle-box swells G G (of whichonly one is shown in Fig.

F 1) are pivoted to the front plate, E, all being cally upon one side.

hinged upon a pin, (2, which passes through eyes therein.

H is the leaf-spring for pressing the swell against the shuttle. It isfastened to the plate E by a screw, f. The ends of the swells extendover the plate F, and are confined by a pin, a, passed through posts J Jon said plate, so that the swells cannot move forward of this pin. Asthe swell moves upon its pivot every time that a shuttle enters orleaves its box, it is found in practice that, as ordinarily constructed,the pivotal hole in the swell wears unevenly by constant working uponits pin, becoming in time elongated or worn eccentri- To avoid thisdefect, I provide the plate E with a hood or cover, 0, in which theknuckle of the swell is housed and against which it is re-enforced asthe swell moves. This cover is preferably cast in one piece with theplate, being formed as best shown in Figs. 6 and 8. Theknuckle of thehinge is confined in this cover, and as it wears upon its pin it bearsagainst the cover, which divides the wear and keeps the hinge frompressing always against one side of the pin.

Fig. 9 is an elevation of a guide-piece, K,

which is useful only in guiding the shuttle-- boxes in their up and downmovement, being fastened to the back of the boxes in the position shownin Fig. 3, and working in the frame of the lay. The back plate, 0, haslong slots 19 1) extending into it from one end for the picker to workin.

My improved shuttle boxes have the advantage of greaterstrength, lessweight, and neater appearance than those heretofore made, besides beingcheaper to construct. As the boxes are made up of small and fiatsections, these can easily be smoothed or finished before putting themtogether.

My invention is subject to modification from the precise constructionshown, although that is the preferable one. The metal sections may beput together otherwise than by riveting, if desired.

My invention applies to the construction of any number of boxes in atier, or even to single boxes.

I am aware that the shelves and bodies of shuttle-boxes have been madeof sheet metal or metal plate, and that boxes have been made ofdifferent pieces of metal fastened together.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is the following-defined novel features orcombinations, substantially as hereinbefore specified, namely:

1. The sheet-metal blank from which the back, top, and bottom of theshuttle-boxare formed, the same consisting of top and bottom portions,Zm, having fastening projections b b, and the-body of the blank havingapertures or slots 11 a for the attachment of the horizontalshuttle-supporting shelves.

2. The sheet-metal blank from which the back, top, and bottom of theshuttle-box are formed, the same consisting of top and bottom portions,Zm, having fastening projections b b, and parallel strips separated byslots 19 p, said strips having apertures a a for the attachment of thehorizontal shuttle supporting shelves.

3. In a shuttle-box, the back plate of metal bent rectangularly at topand bottom to form the top and bottom of the box, said top and bottomhaving fastening projections, in combination with front plates havingaperturesin which said fastening projections fit, whereby said frontplates are fastened to said top and bottom.

4. In a shuttle-box, the back plate of metal bent rectangularly to formthe top and bottom of the box, said back plate having apertures thereinand said top and bottom having fastening projections, in combinationwith front plates having apertures in which said fastening projectionsfit,-and horizontal shelves having fastening projections which fit inthe apertures in said back plate, substantially as set forth. ,7 v

5. Shuttle-boxes made of a thin metal back plate, two front plates atopposite ends, the one at the entering end being extended beyond theback plate and curved outwardly, and horizontal shelves fastened betweenthem.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
